WOOL AND THE LIKE WASHING MACHINE.

Specification of Letters Patent.

Patented May 30', 1916.

Application filed November 26, 1916. Serial No. 83,818.

To all whom it may concern:

Be it known that I, Fanoaaiox Boaroao ln'rmn, a subject of the King of Great Britain, rcsidin at Rochdale, in the county of Lancaster, Lngland, have invented certain new and useful Im rovements in Wool and the like Washing achines; and I do hereby declare the followin to be a full, clear, and exact descri tion 0 the invention, such as will enable ot ers skilled in the art to which it appertains to make and use the same.

My invention relates to im rovements in the conveying means employe in the lower part of the bowl or bowls of wool and the like washing machines for the purpose of mechanically continuously removing the foreign matter accumulating in a trough at the bottom of the bowl to a valve controlled outlet and discharging the said matter from the said outlet.

My invention has for its object to render the said means more efficient, to cause the liquor in the bowl to be practically maintamed always in an even condition throughout the operation and consequently the wool or the like to be washed uniformly.

My invention has also for its object to prevent the foreign matter from accumulating on the sides of the bowl and cause it to descend to the bottom of the bowl for removal by the said means. To this end I employ at the bottom of each bowl one or more mechanically operated conve ers in combination with a valve controlle outlet arranged either at one or both ends or in the middle of the said trou h into which the said foreign matter is do ivered by the said screw-conve ers. The said outlet or outlets I provide with a valve operated periodically by suitable automatic means. To prevent as hitherto the accumulation of foreign matter at the sides of the bowl I employ in the lower part thereof an agitator suitably actuated, and constructed as hereinafter described.

I attain these objects by the mechanism illustrated in the accompanying drawing, in which- Figures 1 and 3 are side elevations partly in section and Fi s. 2 and 4 cross sections thereof at lines --A and B-B respectively. Figs. 5 and 0 are respectively a detached side view and an and view on an enlarged scale of the means for operating the outlet valves periodically automatically.

Similar letters refer to similar parts throu hout the several views.

Re erring to Figs. 1 and 2., according to one embodiment of my invention, 1 form the bottom of the bowl a in the middle with a trough b extendin from end to end of the bowl in which troug i I employ a screw-con veyer c, in combination with an outlet arranged at one end thereof, preferably hopper shaped and controlled by a valve 0 into which outlet the foreign matter is delivered by the screw-conveyer c. When opening the valve e any foreign matter lying in the outlet d is flushed out with some of the liquor contained in the bowl.

Referring to Figs. 3 and 4 according to another embodiment of my invention in some cases I may employ in the trough b, two or more of the screw-conveyers c, having a left and a right hand screw thread, in connection with an outlet d and outlet valve e arranged in the middle thereof, as shown in the present instance. The said screw-conveyer (or conveyers) may be driven in any suitable manner say from the squeezing rollers or the driving shaft of the machine and the said valve operated periodically b hand, as shown in Figs. 2 and 4, or pre erably by suitable automatic means in such a manner that the same will be caused to remain always open for the same length of time and consequently discharge approximatel always the same guantity o liquor. 0 this end and reerring to Figs. 5 and 6, I mount adjacent to the outlet valve e in bearings f, a driving shaft 9 which has secured thereon a chain wheel Ii driven from any suitable rotating part of the machine. ()n the shaft 9 is also secured a disk 1' having a lifting rojection A: and a bevel wheel Z 1n gear witi another bevel wheel m secured to the upper end of a vertical shaft n mounted in bearings 0. The lower end of this vertical shaft has secured thereto a worm 7) in gear with a worm wheel g secured on a horizontal driven shaft 1' mounted in bearings .51 and having also slidably keyed thereto a series of disks at each of which has lifting projections u which vary in number. Above the disks t is suitably fulcrumed a lever 11, near its free end furnished with a projection to adapted to be operated upon by one of the lifting projections u on the (iske t in register thorowith. To the other end of the lover v is pivoted a link w having pivotally connected ill) lOl

thereto a lever arm 1 extending over the disk i and the other end of which is pivoted to the rod 2 of the said outlet valve. This lever arm is provided with a projection 2 adapted to be operated upon by the liftmg pro'ection 1.: of the disk i. The ratio of the sai bevel and worm and worm wheel gearing is such that the shaft 1' will revolve much slower than the driving shaft g, say make one revolution to 30 revolutions of the driving shaft 9. While the said outlet valve is closed, the parts operating the same, are in the position shown in Figs. 5 and 6. \Vhen one of the disk )ro'ections u meets the lever projection w, t e lever 11 is caused to turn on its fulcrum and the link :0 pulling down the rear end of the lever 3/, its projection 2 is brought into the path of the disk projection k and the latter then raising the lever y and the rod 2 connected therewith, the said outlet valve is opened.

The disk projections u are so proportioned that they hold the lever 'l) in its ralsed position sufficiently long to operate the lever y and thus cause the said outlet valve to be opened. As soon as the disk projection It has passed the lever projection 2, the lever y drops into its normal position and the rear end of the lever y is raised by the link a: which lifts the lever projection -w out of the path of the disk projection u and thereby allows the outlet valve rod 2 to drop and thus close the said valve.

Referring again to Fig. 4, if deemed necessary, I may also emplo an agitator in the bottom compartment 0 the bowl a to prevent the foreign matter accumulating on the sides thereof and to cause it to descend to the conveyer (or conveyers). The said agitator consists of an oscillating shaft 3 furnished with arms 4 carrying paddles 5.

I claim:
